How Neurons Communicate

     Neurons communicate through an electrochemical process. Sensory receptors interact with stimuli such as light, sound, temperature, and pain which is transformed into a code that is carried to the brain by a chain of neurons. Then systems of neurons in the brain interpret this information. The information is carried along axons and dendrites because of changes in electrical properties which we call action potential. An action potential is initiated when a messenger attaches itself to a receptor. When that occurs, an electrical signal is triggered to be generated through the neuron. Once the signal reaches the end of an axon, which is at the end of a neuron, a neurotransmitter is released and the process repeats.
